This article presents a case of and reviews the literature involving the extraoral approach for surgical removal of an ectopic mandibular third molar tooth. Case reports describing extraction of the mandibular third molar using the extraoral approach are very limited. This article describes an unusual case of an impacted, infected, ectopic right mandibular third molar that was positioned at the inferior border and had caused an extraoral draining sinus. Furthermore, the roots were intimately involved with the inferior alveolar nerve (IAN) and had perforated the buccal cortex of the mandible. Surgical removal using a transcervical submandibular approach was deemed necessary to try to preserve the IAN and avoid fracture of the mandible in this 74-year-old patient.
本文介绍了一例采用口外入路手术切除异位下颌第三磨牙的病例，并对相关文献进行了综述。描述采用口外入路拔除下颌第三磨牙的病例报告非常有限。本文描述了一例罕见病例，一颗位于右下颌下缘的阻生、感染、异位第三磨牙导致了口外引流窦。此外，牙根与下牙槽神经（IAN）紧密相连，并已穿透下颌骨的颊侧皮质。对于这位74岁的患者，认为有必要采用经颈下颌下入路进行手术切除，以尽量保留IAN并避免下颌骨骨折。
